To all whom it may concern.

,Be it; known that. I, l-lonarro GIL MOR,

'Washingtomi-n the Districtaof Columbia,

shave invented anew and useful lmproveings.

This invention relates ;.to rail anchors,

: anticreepers, or devices forpreventing the :creeping of the rails-of,railways rand ,one

ofits objects is to form a simple device which may be attached to orused inconnection witlrthe tie plate and which AVlllilJB lseflieient inpreventing the creeping action.

Another object is to provide a device which shall be eflicient in:resisting the tend- .ency of. the rail to ,move in either: direction.

:The invention is illustrated in a preferred 1 embodiment. in the.accompanying..drawing,

in which .Jigure l'isianzend viewshowing. the rail in section.

Fig. 2 is a plan viewof the device in' position upon the rail.

:Jl ig. 3 is a.sectionalwiewshowing-the parts in one-of the-positionsassumed during the placing of the device upon the rail.

b llllllfll letters refer to similar parts throughout the several views.

-In the embodiment of the invention illustrated in the drawings, Arepresents the rail having a head portion B andabase portion U, whichrests'upon the tie plate .D.

The tie plateD inturn is supported. by the tie E, a portion of. one ofwhich isshown g in the drawings, .andis secured thereto...by

the spikes or screws F.

The spring G is preferably formed? from 40- a sheet or plate and has aportion 1, which is provided withtwoarms or flanges K, :and is-arrangedto be forced. into an aperture L in the tie plate D between the edge ofthe rail baseC and the tie plateD so th:? the corners-M 'will bitezintothe rail edge. The arms or flangesK are tapered rtN' to facilitateentering and forcing the portion I of the springG between the rail andthe tie plateD. .Thespring G also has aotwo-arms or-flanges' O; which,whenthe spring is in the operative position have corners P engaging' theupper surface :of the rail vloaseC. :At'the upper endiof the spring Gthere aressurfaces. Q which-zem .gagethe:undenside;of.;the;headi;oftherail. .The portion... I of; the spring..G. is. connected gto. the body of;thegspringibyrthetrelatively fiatportion R. The tie: pilateL,D.-may havega -rib;S arranged totengageone;ed-ge' of the .:rail base;;and. .,the. aperture. L:may. be providedwithgspecial stiffeningT to increase the bearing of the portion. Iof-the spring G with the tie plate D.

.=The.device is placed in position-by entering the portionlofthe springG in the aperture L of the tie plate D, which has already been placedupon the tie and secured thereto by the spikes or screws T and drivingor otherwise forcing itdown :so that the arms orflanges'K are: forced inbetween the rail edge and the tie plate-with'the corners M bitingintotheedgeof-therail base until :the lower edges of .the arms or.flanges 0 bear upon the upper corner of the. rail base QOas illustratedinFig- 3. This forces the rail. base edge opposite the portion 1 of thespring into contact with the rib -S of the 5 tie plate D orwiththespikes F if there be ..norib andcauses the railedge, tobe gripped .bythe biting .cornersUh-fof. the. arms. K of :theportionl. 'lVhen thedevice is inthis position the surfaces Qof the upper endof athespring-G-will be about to engagewith ithe under side of the head Bof the railand byforcing the upper portion'ofzthe spring LG. transverse.:.tothe-rail, either by driving yitwith a ham-meror by the use of a suitablewrench the spring G may be forced to the.

final operative. position: shown in Figs. 1 --andu2. "While. beingsoforced transversely of the-rail the portion R ofthe spring G tacts-asaflat spring and thearnis 0 also "formw-ith thebody of the spring G aspring and as' the-arms 0 contact with the upper surface of the railbase C theportion of the spring vGr; formed by'that part of the body;and the; arms 0 tends to flatten somewhat with the cornerv P ofthe arms0 ineontact with the upper surface of the rail base; and 'in the finaloperative position of the parts, shown in=Figs. 1 and 2, thespring G is.pressin-gathe surfaces Q'upwardly against the underside of the railhead B by the-combined spring action ofthe fiat springpor- 'tiOH R andthe spring action of theportion -.:carry-ing the arms 0 and,- attheisainet-ime, the spring G is:pressingdownwardly;upon atherupper-.sur;tacerof the-..-r.a;il;b.ase .0 and the spring G, intending toresume the form from which it has been sprung, locks the parts inposition, the rail head B preventmg any upward movement of the-spring Grand the engagement of the portion I with the tie plate preventing anylateral movement of the spring G.

It will also be readily seen and understood that if the grip of thedevice upon the rail is not sufficient when the parts have been placedin their operative position to withstand the forces tending to move therail or cause it to creep, very slight movement of the rail in relationto the tie plate will cause deflection of one or the other of the arms K(depending upon the direction in which the rail tends to move) and alsoof the arms 0 and that this will increase the biting effect of thebiting-corners M and P upon the edge and upper surface of the rail baseC and thus automatically increase the resistance of the device tofurther movement of the rail.

It will also be seen that the device will be eflicient in preventingmovement of the rail in either direction.

While I have described the invention as embodied in a preferredconstruction, modifications might be made without departing from theprinciples of the invention. Therefore, I do not wish to be understoodas limiting the invention to the particular construction, arrangementand devices shown and described, except so far as these limitations arespecifically set forth in the claims herein.
